The GALAX GeForce RTX 4080 SUPER SG graphics card is packaged in a standard cardboard box, featuring prominent branding elements such as the GeForce RTX and GALAX logos, along with a distinctive hooded figure representing the 'Serious Gaming' series. The contents, including the graphics card and accessories, are securely encased in foam within the box. Included with the graphics card are several accessories and manuals. While these components may not be essential for experienced users, they can be beneficial for a broader gaming audience. The accessories comprise an additional 1-clip booster fan, ARGB/RGB cable headers, a 16-pin to 3 x 8-pin cable connector, and an RGB-Lit anti-sag stand.


Upon unpacking, the focus shifts to the graphics card itself. It has a substantial size and weight, approximately 1.8kg, and dimensions of 335 x 153 x 66 mm. The card occupies 3.5 slots in a computer case, indicating its considerable size for installation.


The NVIDIA GeForce RTX 4080 SUPER is a refresh successor in the ADA series, and is set to replace the current Ampere based 4080. This graphics card is equipped with 16 Gigabytes of GDDR6X memory, operating at an effective data rate of 23  Gbps. This configuration results in a memory bandwidth of 736 GB/sec. Detailed insights into the product's features and specifications are provided in the subsequent sections. While last-gen GeForce RTX 3080 Ti featured 10240 stream/shader processors, the RTX 4080 SUPER also offers  10240  shading cores and delivers markedly higher performance. 


NVIDIA exclusively provides power adapters for the RTX 40-series graphics cards, applicable to both Founders Edition and custom designs by partners. The 12VHPWR connector has recently been a topic of discussion due to isolated overheating incidents, potentially linked to cable bending, user installation, or quality control issues. However, these connectors generally maintain a safe temperature under normal usage conditions.


The GeForce RTX 4000 series, while adhering to PCIe Gen 5 specifications, operates using a PCIe Gen 4.0 x16 host interface. Similarly, the RTX 4080 / SUPER 16GB GDDR6X memory, with its 256-bit wide memory bus, offers significant bandwidth and storage capacity. Despite its 320W Total Graphics Power (TGP), a 650-watt power supply is recommended, although the actual power consumption typically ranges between 275-300 Watts. Keep in mind that board partners may allow for higher TGP, potentially leading to increased power usage in certain configurations, alongside a notch of extra performance of course. The RTX 4080 SUPER  card exhibits a nicely crafted design with a triple-slot thickness and as you can see, it has a lot of cooling real estate.
